Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If projection position and range are fixed, then device complexity is reduced, but user immersion and presence are limited

Engineering Contradiction:

Improveprojection area adaptabilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the projection area based on real-time analysis of image content. The projection area is not fixed but changes according to the analyzed characteristics of the input image, allowing the system to adapt to different content types while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs a feedback mechanism where the image analysis unit continuously analyzes the input image content and provides information to adjust the projection area. This closed-loop control enables the projection area to automatically adapt to image content without requiring complex manual configuration.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If projection area is dynamically adjusted based on image content, then user immersion is enhanced, but processing time increases

Engineering Contradiction:

Improveprojection area adaptabilityVSAvoidimage processing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of the input image content to determine the appropriate projection area before actual projection begins. By analyzing image characteristics in advance and pre-determining the projection parameters, the system minimizes processing delays during the projection process itself.

Inventive Principle:

Principle #10Preliminary action

3Extent of automation

If projection position is adjusted based on distance information only, then automatic adjustment is achieved, but content-based optimization is lost

Engineering Contradiction:

Improveautomatic projection adjustmentVSAvoidcontent-based projection optimization

Core Design Contradiction:

Extent of automationVSAdaptability or versatility

Solution Approach 1:

The image analysis unit performs multiple functions simultaneously: it analyzes image content characteristics, determines optimal projection areas, and identifies objects within the image. This multi-functional approach enables the system to achieve both automatic adjustment and content-based optimization through a single integrated analysis process.

Inventive Principle:

Principle #6Universality (Multi-functionality)
